Flux re-estimation initiated from 200 random starting points. The fluxes which were successfully re-estimated lie on the 1:1 line when plotted against true flux values (A). Correlation analysis by plotting the transaldolase (TA) [0, 1)-flux re-estimates (Ï•4r) versus those of transketolase 1 (TK1) (Ï•3r) (B) and the [0, 1)-flux re-estimate of TK1 (C) as well as of TA (D) versus Ï•2rof glucose 6-P isomerase. The dotted line indicates the solution of Ï•3r= 0.4337 and Ï•3r= 0.6341, respectively.
